A communication system includes a talking doll arranged to speak to a user and to request the user to carry out various tasks. The user responds to such requests by selecting and pressing keys on a remote keyboard. The doll and the keyboard communicate using infra-red signalling. The system is programmed so that the doll can respond to the user's selection and to say whether the selection is correct or not.
